Our first rock sill installation was in Trout Creek in 1995. The intent of these structures is very similar to the digger logs, but can be used in much larger watercourses, narrowing and deepening over widened streams and rivers. Once the rock sills have done their job, and nature has taken over, they tend to blend into the substrate and stream bank, and disappear from view. We have rock sills on Smith's Creek and the Millstream River as well.
- Increased fish habitat availability
- Increased stream channel stability
- Improved substrate and water conditions for fish including increased dissolved oxygen and lower water temperatures
- Reduces the risk of the formation of ice jams
